A scientist who has developed a new ray that can make any country invincible against aerial attacks (don't ask me how) gets kidnapped in Rome. Agent Sigma 3 (with such a code name, no wonder we never heard from him again!) is sent to find him, and his mission takes him from Rome to Tangiers to Barcelona. When you have finished with the front line of Eurospy flicks, you can move on to the second. When you have finished with the second....and the third....and the fourth line, you can move on to stuff like "Agent Sigma 3". A hero without much personality, a very boring story, and a couple of overlong musical numbers make this quite a chore to watch, with the only interest coming from a few fairly unorthodox fight scenes. * out of 4.
